I CLOCK WINDING DEVICE.

Application filed December 20, 1912.

To all'whom it may concern:

Be it known that I, CLARENCE T. HARDT, a citizen of the United States, and a resident of Salisbury, in the county of Rowan and State ofNorth Carolina, have invented a, new and Improved Clock Winding Device, of which the following is full, clear, and exact description.

An object of my invent-ion is to provide aclock-winding device in the form of a selfcont-ained unit attachable to the spindle of the winding barrel of the clock, and bodily removable therefrom when desired. it is desirable in attachments of the character referred to, that the winding device be applicable to the spindle within a space which is usually'available directly back of the dial. In order that the unit may be readil accommodated in the limited space available, and the parts be assembled within small compass, I employ a counter-balanced frame which is disposed vertically when in use, ,ie counterbala-ncing weight being at the lower end, and the upper end of the frame having a laterally deflected arm, the free end of which is ofi'setfrom the body of the frame a distance to permit a pull string for operating the winding attachment to drop straight downward at one side of the frame. Between the lower end and the upper arm for the pull string, the frame is made open, its sides being spread'apart, providing cheek pieces which receive between the r: a ratchet wheel. (Io-acting with the ratchet wheel there is a pawl of a novel form and arrangement, which normally gravitates away from the ratchet wheel, being carried for the purpose on a lateral arm of the frame adjacent to the ratchet and at the side of the frame opposite that to which the pull string is attached. Because of the special arrangement of the pawl, the attachment is adapted for employment either with a clock mechanism in. which the spindle turns back ward as the clock unwinds, or for mec' anism in which the spindle remains ary while the clock unwinds.

The invention will be more particularly described in the specific description herein-- after to be given.

Reference is to be had to the accompanying drawing forming a part of this specification, in which sim-ilarcharacters of reference indicate corresponding parts. in both views. 7

device embodying my invention, illustrating the same in connection with portions of a clock including the spindle of the Winding barrel; and Fig. 2 is a side view, on an enlarged scale, with parts broken away.

In constructing the self-contained winding unit in accordance with my invention, a frame is constructed having an enlarged lower end 10, to give increased weight at said end, and constitute a counter-balance for the frame. The upper end of the frame is in the form of an arm 11, which is ofiset laterally, preferably on curved lines, the outer free end 12 of said frame being pro-- jccted a suihcient distance from the body of the frame so that the pull string 13 may be attached to the end 12 to drop straight down at one side of the broadened and weighted end, 10, as clearly shown in Fig. 1.

Between the weighted-lower end 10 and the arm 11. the frame is made open, as shown best in Fig. 2, and consists of spaced cheeks 14:. Desira'bly the frame, including the weight 10, the upper arm 11 and checks 14, is composed of two members, one terminating as atlo, just above the checks 14, and being riveted as at 16 to the companion plate. Below the cheeks 14, both members of the frame lie close together, as at 17 (Fig. 2), and are given the same shape, which is preferably round, as illustrated in Figs 1. Additional rivets 1S and 19 may be employed below the cheeks 14 to unite the members together. In the cheeks 14; a hub 20 is journaled, carrying a ratchet pinion 21, the said hub having an axial bore to fit over'the winding spindle of the winding barrel 23 of the clock, the framework of which clock is partially indicated at the clock spring being; indicated at The hub of the ratchet pinion may be secured to the spindle in any suitable manner, as by a set screw, one arrangement of which is indicated at 26.

(lo-acting; \v'th the ratchet pinion 21 is a pawl 52?, which is in the form of a U-shaped yol-ze, the ends 28 oi the arms of which yoke are p: ed through the arms l formed on cits 14- at a 1 :int above the pinion 21, i to hold the yoke in place, while per-iii W it to swing. The projection of the us 1 beyond the its 1% is such that the pawl 27 will hang verti Cally when the winding frame is in the nor:
